My son, Brian in SM #426, just uploaded via my Vimeo account his view of the Group 2 start at Portland. If watch closely you can see Duane's #57 kick up dust at 12 before smashing into the tire wall.
Smashing is such as harsh word. It felt like I just grazed the wall. I'm glad Brian had a good race, although somewhat delayed.
... to come flying back out onto the track just missing someone..not sure who.
